THS6132,pdf(High Efficiency Cl

The THS6132 is a Class-G current feedback differential line driver ideal for full rate ADSL DMT systems. Its extremely low power consumption of 600 mW or lower is ideal for ADSL systems that must achieve high densities in ADSL central office rack applications. The unique patent pending architecture of the THS6132 allows the quiescent current to be much lower than existing line drivers while still achieving very high linearity. In addition, the multiple bias settings of the amplifiers allow for even lower power consumption for line lengths where the full performance of the amplifier is not required. The output voltage swing has been vastly improved over first generation Glass-G amplifiers and allows the use of lower power supply voltages that help conserve power.
